  The generic modify field flow action introduced in [1] has
some issues related to the immediate source operand:

  - immediate source can be presented either as an unsigned
    64-bit integer or pointer to data pattern in memory.
    There was no explicit pointer field defined in the union

  - the byte ordering for 64-bit integer was not specified.
    Many fields have lesser lengths and byte ordering
    is crucial.

  - how the bit offset is applied to the immediate source
    field was not defined and documented

  - 64-bit integer size is not enough to provide MAC and
    IPv6 addresses

In order to cover the issues and exclude any ambiguities
the following is done:

  - introduce the explicit pointer field
    in rte_flow_action_modify_data structure

  - replace the 64-bit unsigned integer with 16-byte array

  - update the modify field flow action documentation
